After installing CentOS 7 Linux testing Virtual Machine in Oracle Virtualbox 6.1 to conduct some testing with php / html / javascript web script pages and use the VM for other work stuff that I later plan to deploy on production CentOS systems, I came to requirement of having a working Google Chrome browser.
In that regards, next to Firefox, I needed to test the web applications in commercial Google Chrome to see what its usercan expect. For those who don't know it Google Chrome is based on Chromium Open source browser (https://chromium.org) whichis available by default via default CentOS EPEL repositories.
One remark to make here is before installing Google Chrome, I've also test my web scripts first with chromium, to install Chromium free browser on CentOS:
[root@localhost mozilla_test0]# yum install chromium

Chromium browser worked however it is much more buggy than Google Chrome and the load it puts on the machine as well as resources it consumes is terrible if compared to Proprietary G. Chrome.
Usually I don't like google chrome as it is a proprietary product and I don't even install it on my Linux Desktops, neither use as using is against any secure wise practice and but I needed this time ..
Thus to save myself some pains therefore proceeded and installed Google Chromium.
Installion of Google Chrome is a straight forward process you download the latest rpm run below command to resolve all library dependencies and you're in:

Once Chrome is installed you can either run it from gnome-terminal
[test@localhost ~]$ gnome-terminal &
Or find it in the list of CentOS programs:
Applications → Internet → Google Chrome
Last step to do is to make Google Chrome easily updatable to keep up VM level on high security and let it get updated every time when apply security updates with yum check-update && yum upgrade
for that its necessery to create new custom repo file/etc/yum.repos.d/google-chrome.repo
[root@localhost mozilla_test0]# vim /etc/yum.repos.d/google-chrome.repo
[google-chrome]
name=google-chrome
baseurl=http://dl.google.com/linux/chrome/rpm/stable/x86_64
enabled=1
gpgcheck=1
gpgkey=https://dl.google.com/linux/linux_signing_key.pub
Now letes import the gpg checksum key
[root@localhost mozilla_test0]# rpmkeys –import https://dl.google.com/linux/linux_signing_key.pub
That's all folks google-chrome is at your disposal.
How to show country flag, web browser type and Operating System in WordPress Comments
Wednesday, February 15th, 2012Reading Time: 2minutes
!!! IMPORTANT UPDATE COMMENT INFO DETECTOR IS NO LONGER SUPPORTED (IS OBSOLETE) AND THE COUNTRY FLAGS AND OPERATING SYSTEM WILL BE NOT SHOWING INSTEAD,
!!!! TO MAKE THE COUNTRY FLAGS AND OS WP FUNCTIONALITY WORK AGAIN YOU WILL NEED TO INSTALL WP-USERAGENT !!!
I've come across a nice WordPress plugin that displays country flag, operating system and web browser used in each of posted comments blog comments.
Its really nice plugin, since it adds some transperancy and colorfulness to each of blog comments 😉
here is a screenshot of my blog with Comments Info Detector "in action":
Comments Info Detector as of time of writting is at stable ver 1.0.5.
The plugin installation and configuration is very easy as with most other WP plugins. To install the plugin;
1. Download and unzip Comments Info Detector
linux:/var/www/blog:# cd wp-content/pluginslinux:/var/www/blog/wp-content/plugins:# wget http://downloads.wordpress.org/plugin/comment-info-detector.zip
...
linux:/var/www/blog/wp-content/plugins:# unzip comment-info-detector.zip
...
Just for the sake of preservation of history, I've made a mirror of comments-info-detector 1.0.5 wp pluginfor download here
2. Activate Comment-Info-Detector
To enable the plugin Navigate to;
Plugins -> Inactive -> Comment Info Detector (Activate)After having enabled the plugin as a last 3rd step it has to be configured.
3. Configure comment-info-detector wp plugin
By default the plugin is disabled. To change it to enabled (configure it) by navigating to:
Settings -> Comments Info DetectorNext a a page will appear with variout fields and web forms, where stuff can be changed. Here almost all of it should be left as it is the only change should be in the drop down menus near the end of the page:
Display Country Flags Automatically (Change No to Yes)Display Web Browsers and OS Automatically (Change No to Yes
After the two menus are set to "Yes" and pressing on Save Changes the plugin is enabled it will immediately start showing information inside each comment the GeoIP country location flag of the person who commented as well as OS type and Web Browser 🙂
